Close but no cigar. Rated 2 out of 5 stars

Uninstalled. After several months of use, I got tired of seeing "no results" from their servers. Like a security company that fails to answer the phone half the time - what good is it? Perspectives is a noble effort and I wish them luck as they move forward.

This review is for a previous version of the add-on (4.2.1-signed).
